What is the basic mechanism of the headphone socket and what is the specific form? Let's give you a detailed introduction.
Headphone socket is also an electronic socket component, which is more common in electronic components. The main audio equipment, TV, MP3, mobile phone, equipment and so on need to use headphone socket. In addition, there are many details to be noted when using headphone sockets. For example, when using headphone sockets, the interface should be careful to prevent damp intrusion, otherwise it may lead to short circuit, which may cause noise when using headphone sockets. Or a silent question.
The following is an introduction to the structure of the headphone socket. I hope it will be helpful to you.
The housing is a headphone socket housing with installation contacts and devices for fixing connectors to the device.
In the headphone socket, the function of the insulator is to use contacts to keep the correct position alignment and insulate the contacts and contacts from the housing.
3. Contact parts.
Contact is the conductive part of the connector, which transfers voltage or signal from PCB or wire to the tail of the product, matches the corresponding contacts of the connector, and the contact structure and the end structure of the contacts change.
Notes on the use of headphone sockets:
1. Headphone sockets can not be replaced by other three or four segments of headphone sockets, because they can not meet the requirements of power amplifier equipment headphone socket wiring, and other specifications of headphone sockets are compatible. .
2. With regard to the connection of two-foot and three-foot headphone jacks, the connection between three-foot and four-foot should not be misconnected, otherwise the use of headphone jacks will cause silence problems.
3. During the use of headphone sockets, attention should be paid to prevent damp intrusion, otherwise it will lead to short circuit, which will lead to noise or silence problems when headphone sockets are used.
4. Headphone socket distinguishes between national standard and American standard wiring. Therefore, before operating the wiring in the headphone socket, it is necessary to know whether the corresponding specifications are national or American standards for the logo. In order to avoid the headphone socket wiring error.
5. Earphone jacks and plugs, but also pay attention not to pull out too hard, otherwise access. In order to avoid strong plug-in, the metal chips in the headphone socket may wear out, and the connection between the headphone socket and the plug may be easy to loosen.
Here is a brief introduction of how to connect the headphone socket and how to use it.
Headphone socket wiring method:
There are many ways to connect the headphone socket. Firstly, the standard wiring of the three-segment headphone socket is usually connected to the left and right channels. However, due to the many specifications of some headphone sockets, the specifications of the five-pin headphone socket are usually used for power amplifier equipment (audio equipment), while the one pin of the connection still corresponds to the ground pin and 23 pins. Correspond to left channel output and speaker line. The last four or five pins are connected to the right channel output and speaker cable.
